ARM: pxa: remove unused board files

2023-01-20T10:23:44Z

The majority of all pxa board files has not been touched in a long time, and no users have spoken up in favor of keeping them around. This leaves only support for the platforms that were already converted to DT, as well as the gumstix and spitz/akita/borzoi machines that work in qemu and can still be converted to DT later.

ARM: 9049/1: locomo: make locomo bus's remove callback return void

2021-02-01T19:44:30Z

The driver core ignores the return value of struct bus_type::remove because there is only little that can be done. To simplify the quest to make this function return void, let struct locomo_driver::remove return void, too. All users already unconditionally return 0, this commit makes it obvious that returning an error code is a bad idea and ensures future users behave accordingly.

backlight: Use backlight_get_brightness() throughout

2020-07-20T09:27:06Z

Introduce the backlight_get_brightness() helper in all video/backlight/* drivers. This simplifies the code and align the implementation of the update_status() operation across the different backlight drivers. Some of the drivers gains a little extra functionality by the change as they now respect the fb_blank() ioctl. Signed-off-by: Sam Ravnborg Reviewed-by: Daniel Thompson Signed-off-by: Lee Jones

ARM: fix lcd power build failure in collie_defconfig

2012-04-03T05:03:44Z

Commit 086ada54abaa4316e8603f02410fe8ebc9ba2de1 "FB: sa1100: remove global sa1100fb_.*_power function pointers" got rid of all instances but one in locomolcd.c -- which was conditional on CONFIG_SA1100_COLLIE. The associated .power field which replaces the global is populated in mach-sa1100/collie.c so move the assignment there, but make it conditional on the locomolcd support, so use CONFIG_BACKLIGHT_LOCOMO in that file.

backlight: add backlight type

2011-03-23T00:43:59Z

There may be multiple ways of controlling the backlight on a given machine. Allow drivers to expose the type of interface they are providing, making it possible for userspace to make appropriate policy decisions.
